JVC TH-A32 Activating the Surround Mode, Creating Realistic Sound Fields, For Pro Logic II modes

Creating Realistic Sound Fields

■DSP (Digital Signal Processor) Modes

DSP modes have been designed to create important acoustic surround elements.

The sound heard in a live house, a hall, a concert, a stadium, or a theater consists of direct sound and indirect sound—early reflections and reflections from behind. Direct sounds reach the listener directly without any reflection. On the other hand, indirect sounds are delayed by the distances of the ceiling and walls.

These indirect sounds are important elements of the acoustic surround effects.

The following DSP modes are provided with this unit.

LIVE HOUSE	: Gives the feeling of a live music house with a
	low ceiling.
HALL	: Gives clear vocal and the feeling of a concert
	hall.
CONCERT	: Gives the feeling of a large hall designated
	primarily for classical concert.
STADIUM	: Gives feeling of an outdoor stadium.
THEATER	: Gives the feeling of a theater.

These DSP modes can be used to add the acoustic surround effects while reproducing stereo analog software, Linear PCM digital software, or Dolby Surround encoded source and can give you a real “being there” feeling.

Note:

On some source signals, DSP mode may not work sufficiently. In that

case, select another preferred DSP mode.
